Recent evidence suggests that replacing saturated fat with unsaturated fat is beneficial for cardiovascular health. This study compared the effects of Brazil nut oil (BNO) and soybean oil (SO) supplementation for 30 days on anthropometric, blood pressure, biochemical, and oxidative parameters in patients with metabolic syndrome (MS). Thirty-one patients with MS were randomly allocated to receive 30 sachets with 10 mL each of either BNO (n = 15) or SO (n = 16) for daily supplementation. Variables were measured at the beginning of the study and after 30 days of intervention. No change in anthropometric and blood pressure variables were observed (p > 0.05). Total (p = 0.0253) and low-density lipoprotein (p = 0.0437) cholesterol increased in the SO group. High-density lipoprotein cholesterol decreased (p = 0.0087) and triglycerides increased (p = 0.0045) in the BNO group. Malondialdehyde levels decreased in the BNO group (p = 0.0296) and total antioxidant capacity improved in the SO group (p = 0.0110). Although the addition of oils without lifestyle interventions did not affect anthropometric findings or blood pressure and promoted undesirable results in the lipid profile in both groups, daily supplementation of BNO for 30 days decreased lipid peroxidation, contributing to oxidative stress reduction.

Dislipidemia em escolares na rede privada de Belém
(Sociedade Brasileira de Cardiologia, 2009-06) RIBAS, Simone Augusta; SILVA, Luiz Carlos Santana da
Background: Currently, childhood dyslipidemia, associated to other non-transmissible diseases such as diabetes, hypertension and obesity, represent a significant public health problem in Brazil. Objective: To investigate the prevalence of dyslipidemia in children and adolescents from private schools in the city of Belem, state of Para, Brazil. Methods: Transversal and prospective study that assessed 437 schoolchildren, paired by sex. The age range was established between 6 and 19 years of age and stratified in four subgroups (6 to 9 years; 10 to 12 years; 13 to 15 years and 16 to 19 years). To obtain the anthropometric variables, weight and height were measured for the calculation of the body mass index and skin folds were measured for the calculation of body fat percentage. The serum lipoprotein profile was obtained through the measurement of total cholesterol, triglycerides, LDL-cholesterol and HDL-cholesterol after a 12-hour fasting period, by enzymatic methods. Results: Of the total number of schoolchildren analyzed, 126 (28.8%) were overweight and 158 (36.2%) presented a high adiposity index. The children (33.6%) presented a higher prevalence of obesity when compared to the adolescents (10.1%; p < 0.001). Regarding the biochemical characteristics, it was observed that 214 (41%) presented some alteration in the lipid profile and that children and adolescents in the age range of 10 to 15 years were the age groups that presented the highest rates of dyslipidemia (34.6% and 25.5%), respectively. Conclusion: These findings demonstrate the importance of establishing an early diagnosis of the lipid profile, mainly if it is already associated to another risk factor, such as obesity.

Fatores de risco cardiovascular e fatores associados em escolares do Município de Belém, Pará, Brasil
(Escola Nacional de Saúde Pública Sergio Arouca, Fundação Oswaldo Cruz, 2014-03) RIBAS, Simone Augusta; SILVA, Luiz Carlos Santana da
This cross-sectional study aimed to identify risk factors for cardiovascular disease in a stratified cluster sample of 557 schoolchildren (6-19 years) in Belém, Pará State, Brazil. Potential risk factors were obesity, hypertension, dyslipidemia, diabetes, smoking, physical inactivity, and atherogenic diet. Socio-demographic and lifestyle variables were tested in a binary logistic regression model. The most prevalent risk factors were overweight (20.4%), dyslipidemia (48.1%), and physical inactivity (66.2%). Children below ten years of age and those from higher-income families and with higher maternal schooling showed greater odds of developing overweight; meanwhile, those with overweight were more prone to developing hypercholesterolemia and hypertriglyceridemia. The findings point to the need to implement strategies to prevent overweight in early childhood, through balanced nutrition and regular physical activity, in order to effectively reduce the prevalence of risk factors in schoolchildren.
